BACKGROUND

There are currently a range of existing ultrasound systems that include wired ultrasound probes connected to visual displays and wireless probes that communicate with visual displays remotely. These systems may be used by a clinician to move the ultrasound probe on a skip surface of a patient to acquire ultrasound images from a patient. The ultrasound images are displayed on a screen of an image processing device (or “console”) of a medical/ultrasound computer system. An ultrasound clinician has to be in physical contact with the medical/ultrasound computer to control images, make annotations, save images, and etc. Also, the clinician may have to move back and forth between the patient and the ultrasound computer in order to work with the images. While this approach is commonly used, it does not provide for an appropriate sterile use of the equipment and does not provide for the sterile use of the ultrasound computer mid-procedure.

Embodiments disclosed herein are directed to an ultrasound probe system to be used for ultrasound imaging as well as for remote control of an ultrasound imaging device. The ultrasound probe system including, in some embodiments, a remote control capability is provided.

In one embodiment, an ultrasound probe may be used as a remote control capable of driving functionality of a medical computer/ultrasound system in accordance with sterile use. This enables a user such as a clinician to control the medical computer/ultrasound system from within the sterile field mid-procedure. In one embodiment, the ultrasound probe serves as a physical control for causing alteration of content display on a display screen, such as a physical control for a screen pointer of the medical computer/ultrasound system. The ultrasound probe is configured to determine its position and movement in order to use this information to control the medical computer/ultrasound system remotely. In one embodiment, the ultrasound probe may be wirelessly connected to the medical computer/ultrasound system.

In one embodiment, determination of positioning and movements of the ultrasound probe may be provided by integrated accelerometers. The ultrasound probe may include a fiber optic component such as a fiber optic probe. The ultrasound probe may also include camera tracking device, which may allow the medical computer/ultrasound system to track movements of the ultrasound probe by the camera integrated into the medical computer/ultrasound system. Additional tracking of movements may be implemented by an infrared (IR) tracking device.

The ultrasound probe system, according to the exemplary embodiments, may be primarily used for ultrasound imaging and analysis of ultrasound images displayed on a screen of an image processing device. As discussed above, the ultrasound probe may be used as means of sterile system control and operation by serving as a remote pointer device during ultrasound imaging procedures.

Referring to FIG. 1 , a front view of an ultrasound probe system including a pressure measuring device is shown. The ultrasound probe system 101 includes an ultrasound probe 100 and an ultrasound image processing device 110. The ultrasound image processing device 110 may receive data and display visual feedback from the ultrasound probe 100 for rendering ultrasound visualization. Connection 130 represents a wired connection in this exemplary implementation. The ultrasound probe 100 may have control buttons 150 that may be used for ultrasound imaging and also for controlling of a screen pointer 140 remotely. As discussed above, the ultrasound probe 100 may be moved by a user such as a clinician in various directions as shown by arrows.

According to exemplary embodiments, the ultrasound probe 100 serves as a physical control for the screen pointer 140 of the ultrasound image processing device 110 (e.g., a medical computer/ultrasound system). Ultrasound probe movement-related data may be obtained by the ultrasound image processing device 110 in a variety of methods including, but not limited or restrict to, (1) a fiber optic probe 51 disposed within the ultrasound probe 100, (2) camera-tracking performed by a camera of or coupled to the ultrasound imaging device 110, such as the integrated camera 120, (3) one or more accelerometers of the ultrasound probe 100, and/or (4) infrared (IR) tracking performed by an IR tracking utility 52 of the ultrasound imaging device 110.

In some embodiments, the ultrasound probe 100 is configured to determine its position and movement in order to use this information to control the image processing device 110 remotely. However, in other embodiments, the ultrasound probe movement-related data is provided to the image processing device 110, which then determines the positioning and movement therefrom. Determination of positioning and movements of the ultrasound probe 100 may be provided by integrated accelerometers.

In a first set of embodiments, the ultrasound probe 100 includes a fiber optic probe 51, such as a shape sensing optical fiber cable, that is disposed within the ultrasound probe 100 and detect movement of the ultrasound probe 100 via a plurality of sensors disposed longitudinally along the optical fiber cable. Each of the plurality of sensors may operate as a reflective grating such as a fiber Bragg grating (FBG), namely an intrinsic sensor corresponding to a permanent, periodic refractive index change inscribed into a core fiber of the optical fiber cable. An optical fiber cable that includes a plurality of core fibers may be referred to as a “multi-core optical fiber cable.” Each sensor operates as a light reflective mirror for a specific spectral width (e.g., a specific wavelength or specific range of wavelengths). As a result, as broadband incident light is supplied by an optical light source and propagates through a core fiber, upon reaching a first sensor of the distributed array of sensors for that core fiber, light of a prescribed spectral width associated with the first sensor is reflected back to an optical receiver within the image processing device 110, including a display and the optical light source. The remaining spectrum of the incident light continues propagation through the core fiber toward a distal end of the optical fiber cable (e.g., the ultrasound probe 100). The remaining spectrum of the incident light may encounter other sensors from the distributed array of sensors, where each of these sensors is fabricated to reflect light with different specific spectral widths to provide distributed measurements.

As a result, the reflected light returns information that allows for a determination of the physical state of the optical fiber cable based on wavelength shifts measured from the returned, reflected light. In particular, strain (e.g., compression or tension) applied to the optical fiber cable results in wavelength shifts associated with the returned, reflected light. As the ultrasound probe 110 is moved by the operator, the gratings of the optical fiber cable experience different types and degree of strain.

For example, with respect to a multi-core optical fiber cable, in response to angular (e.g., radial) movement of the ultrasound probe 100 in the left-veering direction, a first core fiber of the multi-core optical fiber cable with the shortest radius during movement (e.g., core fiber closest to a direction of angular change) would exhibit compression (e.g., forces to shorten length). At the same time, a second core fiber with the longest radius during movement (e.g., core fiber furthest from the direction of angular change) would exhibit tension (e.g., forces to increase length). As these forces are different and unequal, the reflected light from reflective gratings associated with the core fibers will exhibit different changes in wavelength. The differences in wavelength shift of the reflected light signals can be used to extrapolate the physical configuration of the wired connection 130 and the ultrasound probe 100 by determining the degrees of wavelength change caused by compression/tension for each of the core fibers in comparison to the wavelength of a center, reference core fiber that is located along a center axis of the multi-core optical fiber cable. These degrees of wavelength change may be used to extrapolate the physical state (e.g., positioning, movement, orientation, etc.) of the ultrasound probe 100.

In a second set of embodiments, the ultrasound imaging device 110 may include or be coupled to a camera, such as the integrated camera 120 for video tracking of the movements of the ultrasound probe 100 to produce the movement-related data that is converted into movements of the screen pointer 140. In particular, logic of the ultrasound image processing device 110 converts the tracked movements of the ultrasound probe 100 into coordinate data that, in turn, is utilized to move the screen pointer 140 based on the movements of the ultrasound probe 100.

In a third set of embodiments, the ultrasound probe 100 includes one or more accelerometers 49 integrated therein. Upon activation, the accelerometers 49 capture ultraSound probe movement-related data, which may then be provided to the ultrasound imaging device 110 to be converted into movements of the screen pointer 140.

In a fourth set of embodiments, the ultrasound imaging device 110 may include or be coupled to an IR tracking utility 52 (such as a pyroelectric IR sensor) that, upon activation, is configured to obtain ultrasound probe movement-related data by sensing heat emitted by the ultrasound probe 100. The logic 306 of the image processing device 110 may be configured to convert the sensed heat to ultrasound probe movement-related data, which is converted to screen coordinate data. The logic 306 may then cause movement of the screen pointer 140 in accordance with the ultrasound probe movement-related data.

In each of the sets of embodiments described above, logic 306 of the ultrasound image processing device 110 converts the tracked movements of the ultrasound probe 100 into coordinate data that, in turn, is utilized to move the screen pointer 140 based on the movements of the ultrasound probe 100. It should also be understood that any of the sets of embodiments may be combined such that the combined tracked movements may be converted into coordinate data.

Additionally, the processor 30 of the ultrasound probe 100 may provide the movement-related data generated by detection of gestures by a motion detection device (not shown) integrated into the ultrasound probe 100 to control the functionality of the screen pointer 140. In some embodiments, the processor of the ultrasound probe 100 may be configured to control the functionality of the screen pointer 140 by voice commands processed by a voice recognition utility 53 integrated into the ultrasound probe 100. For example, the voice recognition utility 53 integrated into the ultrasound probe 100 may detect voice commands that enable or disable the functionality of the ultrasound probe 100 to serve as a physical control of the screen pointer 140.

Referring to FIG. 2 , a view of an ultrasound probe system used as a remote control for an image processing device and a virtual reality or augmented reality device mid-procedure is shown. As discussed above with reference to FIG. 1 , the ultrasound system includes the ultrasound probe 100 connected to the ultrasound image processing device 110. The ultrasound image processing device 110 may be a special-purpose ultrasound computer system. The ultrasound image processing device 110 may also receive and display a visual feedback from the ultrasound probe 100 for rendering ultrasound visualization. Connection 230 represents a wireless connection in this exemplary implementation. A wireless card or utility is shown as 220. The ultrasound probe 100 may have control buttons 150 that may be used for ultrasound imaging and also for controlling a screen pointer 140 remotely. As discussed above, the ultrasound probe 100 may be moved by a user such as a clinician in various directions as shown by arrows.

The ultrasound probe 100 may serve as a physical control for the screen pointer 140 of the ultrasound imaging system (e.g., a medical computer/ultrasound system) 110. The ultrasound probe 100 may be configured to determine its position and movement and pass the ultrasound probe movement-related data to the ultrasound image processing device 110 to be converted into movements of the screen pointer 140.

In some embodiments, the processor of the ultrasound probe 100 may be configured to control a functionality of the screen pointer 140 by providing the ultrasound probe movement-related data generated by an infrared tracking of movements of the ultrasound probe. The processor of the ultrasound probe 100 may provide the movement-related data generated by detection of gestures by a motion detection device (not shown) integrated into the ultrasound probe 100 to control the functionality of the screen pointer 140. In some embodiments, the processor of the ultrasound probe 100 may be configured to control the functionality of the screen pointer 140 by voice commands processed by a voice recognition utility 53 integrated into the ultrasound probe. The ultrasound image processing device 110 may use an integrated camera 120 for video tracking of the movements of the ultrasound probe 100 to produce the movement-related data that is converted into movements of the screen pointer 140.

The ultrasound system 200 depicted in FIG. 2 includes the ultrasound probe 100 that is wirelessly connected to the ultrasound imaging device 110 to render ultrasound images on the screen of the ultrasound imaging device 100. The ultrasound system 200 also includes an augmented reality device 210 (which may also be a virtual reality device) coupled to the ultrasound probe via a wireless or wired connection and to the ultrasound imaging device 110 as shown by connection 240. The augmented reality device 210 is configured to render ultrasound images to a user and to display the screen pointer 140 controlled by the ultrasound probe 100.

FIG. 3 shows a block diagram of an ultrasound probe system 110 including a console connected to an image processing device. The ultrasound probe 100 (depicted in FIGS. 1 and 2 ) includes an ultrasound probe head 31. In some embodiments, the ultrasound probe 100 may include therein a processor 30 for governing system functionality by employment of a general-purpose operating system 35, memory with a file system 37 (e.g., non-transitory, computer-readable medium), and logic or applications 38 that may be stored in the memory 37 and executed by the processor 30. Some of the logic or applications 38 may provide an application programmable interfaces (APIs) to allow a user (i.e., a clinician or a doctor) to control a screen pointer on a screen 39 of the image processing device 110. A beam forming utility 36, including suitable circuitry is also controlled by the processor 30 to enable signals to be produced, received, and processed. For example, the beam forming utility 36 may produce some signals that may be received by the probe head 31. The probe head 31 passes these signals into an area of a patient and receives some reflected signals. The beam forming utility 36 may process the reflected ultrasonic signals converted into electric signals by the probe head 31 and may convert the electric signals into image data. The image data is passed on to the image processing device 110 to be displayed to a user (i.e., a clinician) on the screen 39. Buttons 43 including a power button and control buttons are provided for operation of the ultrasound probe. However, in some embodiments, the ultrasound probe 100 need not include all components shown, such as, for example, the operating system 35.

In some embodiments, the ultrasound probe is configured to determine its position and movement of the ultrasound probe 100 in order to use this information to control the image processing device 110 remotely. Determination of positioning and movements of the ultrasound probe 100 may be provided by integrated accelerometers 49. A processor 30 of the ultrasound probe may be configured to acquire ultrasound probe movement-related data from at least one accelerometer 49.

The ultrasound probe 100 may pass the ultrasound probe movement-related data to the image processing device 110 to be converted into movements of the screen pointer 140. In one embodiment, the processor 30 of the ultrasound probe 100 may be configured to pass the ultrasound probe movement-related data to the image processing device 110 by using a fiber optic probe 51 integrated into the ultrasound probe 100 and connected to the ultrasound probe 100. The processor 30 may provide the movement-related data generated by detection of gestures by motion sensors 50 integrated into the ultrasound probe 100 and connected to the processor 30 to control the functionality of the screen pointer 140. In some embodiments, the processor of the ultrasound probe 100 may be configured to control the functionality of the screen pointer 140 by voice commands processed by a voice recognition utility 53 integrated into the ultrasound probe 100. Note that the ultrasound probe 100 can include different, fewer, or more components than those listed here, including those components that enable the ultrasound probe to operate in a wireless networked manner with other local or remote image processing devices. The ultrasound probe 100 may be also connected to a remote Electronic Health Records (EHR) system.

Additionally, the image processing device 110 is shown to include a screen 39, the IR tracking utility 52, a processor 300, and the optional integrated camera 120. The processor 300 may include an operating system (or may execute an operating system stored on a memory file system 304) and optical logic 308. The memory file system 304 may also have stored thereon logic or applications 306. As discussed above, in some embodiments, the image processing device 110 may obtain ultrasound probe movement-related data using the IR tracking utility 52 (such as a pyroelectric IR sensor). The logic 306 may be configured to convert the ultrasound probe movement-related data to screen coordinate data. The logic 306 may then cause movement of the screen pointer 140 in accordance with the ultrasound probe movement-related data. The optical logic 308 includes a light source 310 and an optical receiver 312.

The light source 310 is configured to transmit the broadband incident light for propagation over the optical fiber cable. In one embodiment, the light source 310 is a tunable swept laser, although other suitable light source can also be employed in addition to a laser, including semi-coherent light sources, LED light sources, etc. The optical receiver 312 (e.g., a photodetector such as a positive-intrinsic-negative “PIN” photodiode, avalanche photodiode, etc.) is configured to: (i) receive returned optical signals, namely reflected light signals received from optical fiber-based reflective gratings (sensors) fabricated within each of the core fibers of the optical fiber cable deployed within wired connection 130 and the ultrasound probe 100, and (ii) translate the reflected light signals into reflection data, namely data in the form of electrical signals representative of the reflected light signals including wavelength shifts caused by strain.

Having a system that not only provides for ultrasound imaging, but provides for pointer remote control capability to enable a single user to control an image processing device from within a sterile field mid-procedure advantageously reduces a risk of spreading infections.
